Description: Connecting problem
Details:

Hi,
I am getting connected to the PostgreSQL database installed in PC1 from a
PC2 from a Delphi application using the PSQLDatabase component(PostgresDAC
components). I have furnished the following information-
Databasename
Hostname as the IP of PC1
username
Password

I am getting an EAccessviolation exception occuring with message - "Access
violation at address 77C460CB in mudule msvrct.dll. Read of address
00000000".
And then I get a blank popup with a cross marked in red.
I have also edited the pg_hba configuration file as under-
host all all 0.0.0.0 0.0.0.0 trust.
host all all 192.168.5.45 md5

And then the postgresql configuration file as-
# - Connection Settings -

#listen_addresses = '*' # what IP interface(s) to listen on;
# defaults to localhost, '*' = any
port = 5432
max_connections = 100

Can you help me out?
